Sr., a citizen ofthe United States, and resi.

:dent of Chicago, in the county vof Cook and State of Illinois, haveinvented certain new f and usefullmprovements in Dump-Cars, of

which the following isa specification. My invention relates to railwaycars and fhas particular reference to anovel dump 'car'V so'v arrangedas to permit the' discharge of the entire load to eitherside of the ear.

It is desirable'inthe handling of coal, sand, gravel, and other granularmaterial to provide means for dumping the contents of va car. Preferablysuch means should provide for dumping the entire load, and while this isnot uncommon, I believe it to be new -to provide. means forl dumping theentire load to either side of the car utilizingv the weight ofI thematerial itself'for effecting the movement of the dumping doors.

The invention will be more readily understood by reference to -theaccompanying drawings wherein- K Figure 1 is an end elevationofa gondolavear to.v which inventionplias been apv plied;y Fig. 2fis` a transversesectionthrough the carfshowing 'thelfdoors in l normalposition; Fig.v 3.isfajview similarhto FigA 2, 'showing the firstl sten inthefdumpingaetion; Fig. 4 is-a lsimilar"vie-wf'showing the completeddumping movement; and Fig.v 5 is a section on the line 5"-5 of Fig. 2.

Referring more particularly to thedrawings it will be seen that thecar'includes center sills 10 onwhich are mounted needle beams 11 servingto support the side Walls 12 of the car. The oor of the car is composedsubstantially wholly of doors 13 which extend from side to side of thecar and are provided with a central pivot 111 which operates in a slot15 in a bracket 16 which is mounted on center sill cover plate 17. Theends of the doors may be normallyY supported by rack bars 18 movable ina horizontal plane beneath the doors by means of a pinion 19 mounted ona shaft 20 extending to the end of the car and to which a crank 21 maybe fitted. It will be seen that the doors are. normally held in aposition in which the pivot 14 occupies the upper portion of the slot15. At each side of the pivot and secured to the doors are bracketsright Yhand central 'shaft loe-ing'*lit-ld' a ofthe slots Y15.

having slots 23therein. PinsQllfare seated `1n 'the `slots -23,'the pins:being rigidly secured toa vertically-lmovableY rack 'slidable 1n afixed p'ath'in a housing or bearing '26v which `is secured tothecentersills. "A Vpinion 27 engages the "rack bar, all of the"'pinions'in a line being mountedon a'shaft V28 which extends to the'end.othejcar -and carries a star wheel29.

Itjlwi'll be understood in the operationof the device thatone rack-barlis"'i'nte1i1d`edto moveupwardly while` the other move'sgdownwardly. 'Ihave therefore provided means for securing this action, asimpleexemplifi! cation of which means is shown in Figl and comprises a'handlever "30 and lir'i'kfs-fl` 32 the link 32V being rotatable lonptheshaft While adjusting the "paw'l's" 1it I'will be` s'en that the shaftsmay bev moved -in=thesanielor opposite directions,asfdesired. Y

' The -V operationjis asV follows: Assuming rotatiom and theH "eft-`hand* centralfshiift being free to'revolve, it vwillloee seen'ft-hat'the doors willihave a 'tendency ltoj'I-*otate about the right hand`pinuli'gand 'this'-I rotation will be positiveV because offthe` superposed load on the door to the left ofsuch pivot. The doors-will :thendrop tothe position of Fig. 3; 'that"is, tothe Vpoint-'where the doorpivots 14 occupy the lower portion The load having started to discharge,the preponderance will be to the left of the pivot, and upon releasingthe right hand central shaft the door will continue to tilt until itreaches the position of Fig. 4. If this should not occur, the movementof the door may be made positive by actuating the handle 30 andarranging the pawls in such manner that one rack bar is moved upward andthe other downward. If it be desired to dump the load on the oppositeside, the same steps will be taken with the opposite parts.

Obviously the instrumentalities for effecting this result may be changedin many particulars and I do not, therefore, wish to be limited totheconstruction shown and described.

I claim:

1. In a dump car, the combination of car walls and a door extendingsubstantially entirely across the width of the car, a floating pivot forthe door, 'said pivot being located at substantially the center of thecar, and means located at each side of the center of the door a portionof which means is adapted to act as a pivot for the door upon thereleasing of one edge thereof, substantially as described.

2. In a railway car, the combination of side walls and a floor, saidfloor being composed of a series of single doors which eX- tend fromside to side of the car, a vertically shiftable pivot for each of saiddoors, the pivot being located at substantially the transverse center ofthe door, supporting means for the edges of the doors, and verticallymovable pivots located at each side Y of the center of each door,substantially as described.

3. In a railway car, thc combination of a center sill, side walls andHoor, said floor being composed of a series of single doors extendingfrom side to side of the car and provided .with atransversely-centralized pivot, said .pivot being mounted in avertioally-elongated bearing, and verticallymovable stops mounted ateach side of the Vdoor and adapted for vertical reciprocation inopposite directions whereby said doors maybe tilted vand theload'd'ischared to .either side of the car, substantially as described.

.4. In a. railway car, the combination of side walls and a floor, saidfloor being com- .posed of a series of single doors extending from sideto side of the car, means at the outer edges of the doors for normallymaintaining the doors in position, a central pivot shafts whereby tosimultaneously move said rack bars in opposite directions, substantiallyas described.

5. In a. railway car, the combination of side wallsv and a 1ioor, sa idfloor being coinposed of series of doors which extend from side to sideof the car and each door being provided with a central, shifting pivot,vertically-recip-rocable members located at each side of the pivot,means for actuating said members and for releasing one or both thereofas required, the parts being arranged whereby one of said members may bereleased and the door be permitted to pivot on the other member throughdistances vdetermined by said shiftable pivot, substantially asdescribed.

G. In a dump car, the combination of side walls and a floor, the floorbeing composed of a series of single doors which extend from side toside of the car, vertically shiftable supporting devices for said doors,onev of said devices being located on each side of-the longitudinalcenter of the car, said doors being pivoted on said supporting devices,whereby when one of said supporting devices is lowered, the door .willpivot upon the other of said supporting devices, substantially asdescribed.

7. In a dump car, the combination of side walls and a floor, the floorbeing composed of a series of single doors which extend from side toside of the car, vertically shiftable supporting devices for said doors,one of said devices being located on each side of the longitudinalcenter of the car, said doors being pivoted on said supporting devices,Whereby when one of said supporting devices is lowered, the door willpivot upon the other of said supporting devices, and means located atthe outer edges of the door for rigidly supporting the door when inclosed position, substantially as described.
